Isolation Of A 3-Methylindole-Producing Bacterium From A Swine Waste Lagoon, Michelle L. Fusting
Isolation Of A 3-Methylindole-Producing Bacterium From A Swine Waste Lagoon, Michelle L. Fusting
Mahurin Honors College Capstone Experience/Thesis Projects
With an increase in animal production closer to populated areas, odorants from animal waste are a rapidly rising concern. 3-Methylindole (3-MI) is an odorant produced from the biodegradation of L-tryptophan by bacteria in animal waste. Currently, no 3-MI producing bacterium has been isolated from swine waste, and isolation of such an organism would provide insight into production and regulation of 3-MI. Therefore, an experiment was designed to isolate a 3-MI producer based on previous work which indicates the presence of Fe(III) increases 3-MI levels. An Enterococcus sp. was isolated from WKU's primary swine waste lagoon in rich, anaerobic medium plus …
Determining Gene Copy Number In Transfected Caprine Fibroblast Cells, Jessica A. Wilson
Determining Gene Copy Number In Transfected Caprine Fibroblast Cells, Jessica A. Wilson
LSU Master's Theses
Transgene expression in stably transgenic organisms is affected by many factors, including the copy number of the transgene in the genome, and by interactions between the transgene and flanking DNA sequences. Transgene copy number has also been shown to effect genetic stability in transgenic plants. Two commonly used methods for transfecting cells are liposome mediated transfection and electroporation. Little is known about the mean transgene copy number or variability of the copy number with these techniques. Quantitative PCR (Q-PCR) has been shown to be an effective method for determining transgene copy number. The objective of this study was to determine …

Turkish Journal of Zoology
Some ecological requirements of aquatic Coleoptera species were studied in a natural lake. Water beetle samples, collected in 2007 from the National Park Sahara-Karagöl belonging to the families Helophoridae, Hydrophilidae, Hydrochidae, and Dytiscidae were identified and listed. Both physical (conductivity and temperature) and chemical (pH, dissolved oxygen, total dissolved solids, hardness, organic matter, chloride, phosphate, and some metal ions) parameters of the inhabited water were measured.
Multivariate Morphometric Study On Apis Florea Distributed In Iran, Ayça Özkan, Mohammed M. Gharleko, Berna Özden, İrfan Kandemi̇r
Multivariate Morphometric Study On Apis Florea Distributed In Iran, Ayça Özkan, Mohammed M. Gharleko, Berna Özden, İrfan Kandemi̇r
Turkish Journal of Zoology
Multivariate Morphometric and Spatial Autocorrelation Analyses were performed to determine the morphometric variation in Apis florea colonies representing 13 localities from 4 states on the coastal north-south diagonal in Iran. New morphometric characters (hind wing length, hind wing width, and hind wing angles) were also measured to determine the usefulness of these characters for Apis florea. Analysis of variance of new morphometric characters showed that 7 out of the 8 hind wing variables displayed statistically significant differences among populations (P < 0.05). The scatter plot from Canonical Variate Analysis revealed that the colonies from north (Ilam, Khuzestan, and Bushehr states) showed an overlapping distribution. The colonies from south (Hormuzgan state) formed a non-overlapping distant cluster. Based on the spatial autocorrelation analysis, 14 correlograms were significant for morphometric characters (According to the Bonferroni criterion). Six characters (CuB, C.Ind, HWW, B4, D7, and I13) showed clinal type correlogram.

Inheritance Of Shoulder Spotting In The Tetra, Hyphessobrycon Bentosi Characidae, Jack Frankel
Inheritance Of Shoulder Spotting In The Tetra, Hyphessobrycon Bentosi Characidae, Jack Frankel
Department of Biology Faculty Publications
The tetra (Hyphessobrycon bentosi) exhibits two phenotypes associated with shoulder spotting. Fish possess ei-ther a prominent black vertical spot located directly behind the operculum (H. b. bentosi, bentosi white tip tetra) or lack this spot (H. b. rosaceus, rosy tetra). Segregation patterns observed from the progenies of ten different crosses suggest that the inheritance of these phenotypes is controlled by two autosomal loci acting in a complementary fashion, with domi-nance at both loci required for the expression of the spotted phenotype.

Replacing Fertilizer Nitrogen With Dried Distillers Grains Supplement To Yearling Steers Grazing Bromegrass Pastures: Economics And Modeling, Matthew A. Greenquist, Terry J. Klopfenstein, Walter H. Schacht, Galen E. Erickson
Nebraska Beef Cattle Reports
An economic analysis of a three-year study evaluated use of N fertilizer and dried distillers grains plus solubles (DDGS) supplementation to yearling steers grazing smooth bromegrass in eastern Nebraska (Nebraska Beef Report, 2009, pp. 26-28). Costs of gain tended to be lower for cattle on fertilized pastures. Grazing profitability was lowest for cattle on non-fertilized pastures, intermediate for cattle supplemented with DDGS, and highest for cattle on fertilized pastures. The weight advantage (9%) of steers supplemented with DDGS during the grazing period was maintained through the finishing period, leading to greater profitability. Profitability for steers supplemented with DDGS at the …
Dose Titration Of Sericea Lespedeza Leaf Meal On Haemonchus Contortus Infection In Crossbred Lambs, Dana Alicia Pollard
Dose Titration Of Sericea Lespedeza Leaf Meal On Haemonchus Contortus Infection In Crossbred Lambs, Dana Alicia Pollard
LSU Master's Theses
Gastrointestinal nematode (GIN) parasitism is a problem for small ruminant producers. Haemonchus contortus is the most detrimental because of substantial economic losses. Over the past decades, chemical anthelmintics have been used to control GINs. Recently, GINs have developed resistance to most anthelmintics, and now reliance on anthelmintics is not possible. Alternative control methods are needed. Also, the use of fewer chemicals in agricultural products has called for alternative methods to be less synthetic and more organic. One promising alternative method is the feeding of condensed tannin (CT) containing forages as either fresh forage or dried products such as hay, ground …
Characterization Of Porcine Adipose Tissue-Derived Stem Cells, Kellie J. Williams
Characterization Of Porcine Adipose Tissue-Derived Stem Cells, Kellie J. Williams
LSU Doctoral Dissertations
Nuclear transfer (NT) results in low success rates and research has reported problems with the welfare of cloned animals produced. Evidence suggests the use of a less differentiated donor cell, such as a stem cell, may lead to an increase in the efficiency of the NT procedure. Stem cell characteristics must be clearly defined in order to isolate, identify and optimally culture potential donor cells. Stem cell characteristics such as self-renewal and differentiation have not been identified in stem cells from porcine adipose tissue, an easily attainable tissue resource. The phenotypic profile of cell surface proteins and chromosomal stability of …
Effect Of Rotational Or Continuous Stocking Method Of Winter Pasture On Beef Heifer Performance, David G. Skeans
Effect Of Rotational Or Continuous Stocking Method Of Winter Pasture On Beef Heifer Performance, David G. Skeans
LSU Master's Theses
Considerable research has been conducted comparing the effect of continuous and some form of rotational stocking method on animal and forage performance, but most research utilizes put-and-take stocking rates. The purpose of this research was to determine the effect of 12-paddock rotational stocking method (ROT) or continuous stocking method (CONT) of winter wheat (Triticum aestivum) and annual ryegrass (Lolium multiflorum) pastures on beef heifer and forage performance while maintaining a continuous stocking rate of 3.7 heifers/ha. Two experiments were conducted and analyzed separately due to confounding year and location. Heifer ADG and WG/ha tended to be increased by ROT compared …
Population Density, Circulating Testosterone And Dawn Chorus Behaviour In White-Throated Sparrows (Zonotrichia Albicollis), Simon Richard Hall
Population Density, Circulating Testosterone And Dawn Chorus Behaviour In White-Throated Sparrows (Zonotrichia Albicollis), Simon Richard Hall
Theses and Dissertations (Comprehensive)
An integrative approach to biological research has facilitated the study not only of specific phenomena, but of the connections between these phenomena. A particularly striking example is that of the relationships between testosterone, social behavior, and social context. Increased levels of testosterone increase the frequency of aggressive behaviors and reduce the quality of parental care in many songbird species, and these changes in behavior can affect the surrounding social environment. Different social contexts, population density as a readily studied example, affect the cues that control the release of testosterone into the bloodstream. The distinct tan-stripe and white-stripe phenotypic morphs of …

Population Structure Of The Invasive Round Goby In Lake Michigan, Elizabeth A. Larue, Carl Ruetz Iii, Ryan Thum
Student Summer Scholars Manuscripts
The recent establishment of the round goby (Neogobius melanostomus), an invasive fish in Lake Michigan, provides a model system to view fine scale evolutionary and ecological processes that can create genetic structure within a population. We used seven nuclear polymorphic microsatellite markers (N = 11-17 per site) and measurements of fish total length, weight, and sex (N = 20-74 per site) on round gobies captured by minnow traps and angling among 12 sites around the entire shore of Lake Michigan to determine if evolutionary processes are present in Lake Michigan by characterizing population structure of the round goby. Specific objectives …

The Effects Of Feeding Level And Stocking Density On The Growth And Feed Efficiency Of Himri Barbel Fry, Barbus Luteus (Heckel, 1843), Kaya Gökçek, Yalçin Tepe
Turkish Journal of Veterinary & Animal Sciences
Two stocking densities (20 and 40 fry/80-l tank) with 4 feeding rates (2.5%, 5.0%, 7.5%, and 10.0% body weight/day) were used to determine the optimum feeding level for himri barbel fry during a 60-day culture period. Water quality parameters (temperature, dissolved oxygen, pH, and total ammonia nitrogen) were monitored during the experiment. Final body weight and specific growth rate (SGR) was significantly lower with the 2.5% feeding rate than with the others, at both stocking densities; however, no significant differences were observed between the other feeding rates and between stocking densities. The best feed conversion ratio (FCR) of 1.37 was …

Turkish Journal of Veterinary & Animal Sciences
Measurements of biomarker responses in fish from contaminated sites could provide valuable data for environmental risk assessment. Biomarkers are sensitive to both environmental pollution and confounding factors that are not related to pollution (e.g., season, nutritional status, and population density). Unfortunately, data about the latter group are scarce. Therefore, juvenile sterlet (Acipenser ruthenus L.) specimens were collected on a monthly basis from the Danube River from September 2002 through August 2003 to determine if seasonal changes exist in condition, hepatosomatic index, and parasitism. Fulton condition factor (FCF range: 0.27 - 0.79), hepatosomatic index (HSI range: 1.14 - 6.67) and Skrjabinopsolus …

Genetically fat and lean chickens reared identically in the same environment were used to investigate the effect of the apoVLDL-II gene (intron I) on total cholesterol, triglyceride, and lipoprotein concentrations. The overall allele frequency in the 2 populations was 0.59 for allele A and 0.41 for allele B. The allele frequency in the Rugao breed was 0.52 for allele A and 0.48 for allele B; however, in the Anka breed it was 0.65 for allele A and 0.35 for allele B. The apoVLDL-II genotype in the genetically fat Anka breed was associated with a significant increase in serum triacylglyceride concentration …

The objective of this work was to study the protein patterns, plasmid profiles, and antibiotic susceptibility of Staphylococcus intermedius and Staphylococcus aureus isolates originating from mastitic mammary glands of dairy cattle in different parts of Konya province. A total of 114 Staphylococcus species were isolated and identified by conventional bacteriological methods from bovine mastitis. Of the total isolates 77 were identified as S. aureus and 37 as S. intermedius. Intra- and inter-species diversities in the coagulase-positive staphylococci were investigated by analysis of whole-cell protein profiles using sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). Plasmid profiling also demonstrated that 75 S. aureus …
